Printable Pregnancy Diagrams

A handy of free and printable pregnancy diagrams are available in details! For expecting women or anyone who is learning about the stages of pregnancy, these diagrams will be a helpful material to assist you in understanding how pregnancy goes. If an egg meets up with a sperm cell that has made its way into the fallopian tube, it combines into one cell, a process that’s known as fertilization or conception. At fertilization, the sex of the fetus is already determined, depending on whether the egg receives an X or Y chromosome from a sperm cell. If the egg receives an X chromosome, the baby will be a girl; a Y chromosome means the baby will be a boy.

In early stage of pregnancy, it takes about three to four days for the fertilized egg (or embryo) to move to the lining of the uterus, where it attaches or implants to the uterine wall. Once the embryo is implanted, the cells start to grow eventually becoming the fetus and the placenta, which is tissue that can transport oxygen, nutrients and hormones from the mother’s blood to the developing fetus throughout pregnancy. During the first month of pregnancy the heart and lungs begin to develop, and the arms, legs, brain, spinal cord and nerves begin to form. The embryo will be about the size of a pea around one month into a pregnancy.

You can see the details of pregnancy in the pregnancy diagrams above. Around the second month of pregnancy, the embryo has grown to the size of a kidney bean, he explained. In addition, the ankles, wrists, fingers and eyelids form, bones appear, and the genitals and inner ear begin to develop. After the eighth week of pregnancy and until birth occurs, a developing baby is called a fetus. In the second trimester, the fetus is growing a lot and will be between 3 and 5 inches long, Burch said. Somewhere between 18 and 22 weeks an ultrasound may reveal the sex of the baby, if parents want to know it in advance.

During the eighth month of pregnancy, the fetus gains weight very quickly. Bones harden, but the skull remains soft and flexible to make delivery easier. The ninth month is the home stretch of pregnancy and the fetus is getting ready for birth by turning into a head-down position in a woman’s pelvis. The lungs are now fully mature to prepare for functioning on their own. The fetus continues to gain weight rapidly. You can get the diagrams for free by clicking on the images.
